BACKGROUND OF THE INVENTION 1. Field of the Invention

The subject invention is directed to frozen dessert machines, and moreparticularly, to a mechanical interface between a detachablecantilevered baffle and a freezer door of a frozen desert machine.

2. Description of Related Art

Machines for continuously freezing soft serve desserts are well known inthe art Most of these machines operate on a similar principle. A mixtureof milk, sugar, gelatin, flavoring, coloring, nuts, fruits, syrups andsometimes eggs is fed into a metal cylinder or mixing chamber aroundwhich a compressed gas is expanded, making the metal surfaces of themixing chamber very cold. Ice crystals form on the surface of thechamber and they are scraped off by sharp blades revolving around theinterior of the chamber. Part of the scraping assembly is a beatingarrangement that introduces air into the mixture, increasing its volume.The scraping assembly also moves the frozen dessert to the dischargespout associated with the door of the mixing chamber.

In frozen dessert machines sold by Taylor Commercial Foodservice, LLClocated in Rockton, Ill., the scraping assembly is operativelyassociated—with a cantilevered baffle that extends into the mixingchamber from the door of the freezer. In prior art soft serve dessertmachines of this type, the cantilevered baffle is usually made fromstainless steel and it has a threaded protrusion at its end that is usedto affix the baffle to the interior surface of the freezer door, whichis made from a plastic material unlike the baffle.

This metal-to-plastic threaded interface exhibits high field failurerates—when subjected to a typical daily heat treatment cycle, duringwhich the dessert product remaining within the mixing chamber ispasteurized at a temperature of between 150° F. to 160° F, and thencooled. This daily heat treatment cycle places stress on the threadedinterface between the door and baffle, which tends to degrade theplastic door over time.

It would be beneficial therefore, to provide an interface between thedoor and baffle that could withstand the mechanical stress associatedwith a daily heat treatment cycle, and thereby effectively reduce orotherwise eliminate the high field failure rates that are currentlybeing experienced in the marketplace. The subject invention providessuch a solution.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawings wherein like reference numerals identifysimilar structural elements and features of the subject invention, thereis illustrated in FIGS. 1 and 2, two different versions of soft servedessert machines manufactured and sold by Taylor Company, a division ofCarrier Commercial Refrigeration, Inc. located in Rockton, Ill. Theseare examples of the type of machines for which the door and baffleinterface assembly of the subject invention was specifically designed.

More particularly, FIG. 1 shows a soft serve dessert machine designatedgenerally by reference numeral 100 that includes a single spout freezerdoor 110 and a single mixing chamber 112 for blending a dessert product.Similarly, FIG. 2 shows a soft serve desert machine designated generallyby reference numeral 200 that includes a three spout door freezer door210 and two mixing chambers 212 a and 212 b for two different flavors offrozen dessert product. These two machines 100, 200 are merely exemplaryof the dessert machines that are manufactured and sold by TaylorCompany, and should not be viewed in anyway as limiting the scope of thesubject disclosure.

These soft serve dessert machines require scheduled cleaning andsanitizing, often governed by statute and local regulatory agencies.Indeed, many of the soft serve dessert machines manufactured and sold byTaylor Company, such as the machines 100 and 200 illustrated in FIGS. 1and 2, provide a daily heat treatment cycle to safely maintain dairyproducts contained therein up to two, weeks, before a completedisassembly of the machine is required.

During the heat treatment cycle, the dessert product remaining withinthe mixing chambers of the machines is pasteurized at a temperature ofbetween 150° F. to 160° F., and then cooled. This treatment methodincreases efficiency, decreases labor time and costs and reduces productwaste. However, as explained in more detail below, repeated daily heattreatment cycles can cause certain critical components in these machinesto undergo a significant amount of stress and fatigue, which can resultin mechanical failures, taking the machines out of service until theycan be repaired.

Referring now to FIG. 3, there is illustrated the soft serve dessertmachine 100 with certain prior art component parts separated from thedessert machine for ease of illustration. More particularly, FIG. 3illustrates the mechanical components that are associated with thesingle spout freezer door 110 of dessert machine 100. These componentsinclude an elongated cantilevered baffle 116 which is affixed to therear surface of the freezer door 110, an annular door gasket 118 forsealing the freezer door relative to the freezing chamber 142, and acylindrical bearing 120 which slides over the baffle 116 to rotatablysupport the front end portion of a helical beater 122. The helicalbeater 122 includes a plurality of scraper blades 124. The blades 124are configured to scrape frozen dessert product from the interiorsurfaces of the freezing cylinder 142 and move that product toward thespout 144 on freezer door 110.

The mechanical components associated with freezer door 110 furtherinclude a beater drive shaft 126 and a drive shaft seal 128 that sealsthe end of the drive shaft 126 to the rem of the freezing cylinder orchamber 142. The beater drive shaft 126 has a rectangular head portion130 that is dimensioned and configured to fit within a correspondinglyshaped hole 132 on the rear end of the beater 122, to engage the twocomponents together. In use, the beater drive shaft 126 transfers torqueand rotational motion to the beater 120 from a motor housed within thedessert machine 100.

Referring now to FIG. 5, the prior art cantilevered baffle 116 includesa cylindrical hub portion 134 and an elongated U-shaped rod portion 136.A threaded protrusion or post 138 extends from the front end of hubportion 134 for threaded engagement with a corresponding threaded bore140 formed in the rear surface of freezer door 110. The baffle 116 ismade from stainless steel, while the freezer door 110 to which it isaffixed, is made from plastic. This metal-to-plastic threaded interfacebetween the plastic door 110 and the metal baffle 116 exhibits highfield failure rates when subjected to a daily heat treatment cycledescribed above. The subject invention was developed to overcome thisproblem, as explained in more detail below.

Referring back to FIG. 3 in conjunction with FIG. 5, the cylindricalbearing 120 is dimensioned and configured to fit over the hub portion134 of the baffle 116, and it includes a front flange 146 that acts as athrust bearing between the freezer door 110 and the front end of thehelical beater 122, which will tend to exert a force against the freezerdoor 110 when the dessert machine 100 is in operation.

Referring now to FIG. 4, there is illustrated the soft serve desertmachine 200 with certain prior art component parts thereof separated forease of illustration. More particularly, FIG. 4 illustrates two sets ofcommon mechanical components that are associated with the three spoutfreezer door 210 of dessert machine 200. For the sake of brevity, thesecomponents include cantilevered baffles 216 a, 216 b affixed to threespout freezer door 210, annular door gaskets 218 a, 218 b for sealingthe freezer door 210 with respect to the mixing chambers 242 a, 242 b,cylindrical bearings 220 a, 220 b (with front flanges 246 a, 246 b) forrotatably supporting and interacting with the helical beaters 222 a, 222b (with scraper blades 224 a, 224 b), beater drive shafts 226 a, 226 bwhich engage and drive the beaters 226 a, 226 b, and associated driveshaft seals 228 a, 228 b that sealingly interact with the rear of thefreezing cylinders 242 a, 242 b.

Referring to FIG. 6, each of the cantilevered baffles 216 a, 216 b ofdessert machine 200 includes a cylindrical hub portion 234 a, 234 b andan elongated U-shaped rod portion 236 a, 236 b. A threaded protrusion orpost 238 a, 238 b extends from each hub portion 234 a, 234 b forthreaded engagement with corresponding threaded bores 240 a, 240 bformed in the rear surface of the freezer door 210. These baffles 216 a,216 b are made from stainless steel, while the freezer door 210 to whichthey are threadably affixed is made from plastic. Once again, thismetal-to-plastic threaded interface exhibits high field failure rateswhen subjected to a daily heat treatment cycle.

Referring now to FIG. 7, there is illustrated a single spout freezerdoor constructed in accordance with a preferred embodiment of thesubject invention and designated generally by reference numeral 310.Freezer door 310 is designed for use with dessert machine 100 shown inFIG. 1, and it is similar to the single spout freezer door 110 shown inFIG. 3, except that freezer door 310 has a generally U-shaped recessedmounting pocket 350 formed in the interior or rear surface thereof.

The recessed mounting pocket 350 is located within the periphery ofannular groove 352 that accommodates the door gasket 118, which is shownin FIG. 3. A cornice 354 covers an upper portion of the mounting pocket350. The cornice 354 is attached to the rear side of the freezer door310 by a pair of threaded fasteners 356, as shown. Alternatively, thecornice may be formed integral with the rear side of the freezer door310, as described in more detail below with reference to FIGS. 10 and14.

Referring to FIG. 8, there is illustrated a cantilevered baffleconstructed in accordance with a preferred embodiment of the subjectinvention and designated generally by reference numeral 360. Unlike theprior art baffle 116 described above and shown in FIG. 5, baffle 360 ismolded from a plastic material, not stainless steel. Preferably, thebaffle 360 is formed from a self-lubricating thermoplastic material,such as, for example, Delrin, which exhibits high stiffness, lowfriction and dimensional stability when subjected to heat.

The baffle 360 has a one-piece integral construction that includes acylindrical front hub portion 362 having, an annular thrust bearing 364,an elongated central portion 366 and a generally cylindrical supportregion 368. The central potion 366 of the baffle 360 has a generallycruciform cross-sectional configuration, which is best seen in FIG. 8A.The cruciform shape aids in mixing dessert product within the core ofthe beater 122, and is an enhancement over the U-shaped portion 136 ofprior art baffle 116. In an alternative embodiment of the baffle 360,the elongated central portion 366 has a generally trilobularcross-sectional configuration, as illustrated in FIG. 8B, which is alsoan enhancement over the prior art baffle 116.

The front hub portion 362 of baffle 360 supports rotation of the frontend of the helical beater 122 and the integral thrust bearing 364provides a bearing surface between the front end portion of the beater122 and the freezer door 310. The cylindrical support region 368 ofbaffle 360 interacts with the beater drive shaft 126 to aid in keepingthe baffle 360 concentric with the beater 122 and the freezing cylinder142. By integrating these mechanical features into the one-piece baffle360, there is a reduction in component parts relative to the prior artmechanical assembly shown in FIG. 3.

With continuing reference to FIG. 8, the front end of the baffle 360 isformed with a retention flange 370 that has a generally U-shapedconfiguration, which corresponds to the U-shaped configuration of therecessed mounting pocket 350 in the freezer door 310 shown in FIG. 7.More particularly, the retention flange 370 is dimensioned andconfigured for reception within the mounting pocket 350 of the freezerdoor 310 behind the cornice 354, as best seen in FIG. 9. It should beappreciated that an upper edge 372 of the retention flange 370 of baffle360 is rounded or beveled, and a lower edge 374 of the cornice 354covering the upper portion of mounting pocket 350 in freezer door 310 isangled or beveled (see FIG. 11). This eases the engagement of theretention flange 370 behind the cornice 354 of the mounting pocket 350,which will be described in more detail below with reference to FIGS.11-13 below.

The U-shaped interface between the retention flange 370 of baffle 360and the mounting pocket 350 of freezer door 310, prevents the baffle 360from rotating relative to the freezer door 310 when the beater 122 is inmotion during machine operation. Moreover, this plastic-to-plasticinterface, which is shown in FIG. 9, is not susceptible to the stressand fatigue that has impacted the metal-to-plastic threaded interface ofthe prior art metal baffle 116 and plastic freezer door 110, as a resultof repeated heat treatment cycles.

FIG. 10 illustrates the same mechanical interface described above as toFIG. 9, but for a three spout freezer door 410 designed for use withdessert machine 200 shown in FIG. 2, which supports two of cantileveredbaffles 360 a, 360 b. Here, the freezer door 410 of the subjectinvention has two generally U-shaped mounting pockets 450 a, 450 bformed in the interior or rear surface thereof. The mounting pockets 450a, 450 b corresponding to freezing cylinders 242 a, 242 be of frozendessert machine 200. As an alternative to the separate cornice 354 shownin FIG. 9, the embodiment of FIG. 10 provides integrally formed cornices454 a, 454 b covering the upper portions of mounting pockets 450 a, 450b.

Referring now to FIGS. 11 through 13, there are illustrated a series ofside elevational views, in cross-section, that illustrate the method ofaffixing the cantilevered baffle 360 to the freezer door 310 of frozendessert machine 100, in accordance with a preferred embodiment of thesubject invention. More particularly, FIG. 11 shows the initialpositioning of the beveled upper edge 372 of the retention flange 370 ofbaffle 360 below the beveled lower edge 374 of the cornice 354 ofmounting pocket 350 of the freezer door 310.

FIG. 12 shows the initial engagement of the retention flange 370 ofbaffle 360 behind the cornice 354 of mounting pocket 350, and FIG. 13shows the angular pivoting of the baffle 360 into a final detachablyengaged position of the retention flange 370 of baffle 360 within themounting pocket 350 of freezer door 310, securely retained behind thecornice 354. This plastic-to-plastic mechanical interface assemblybetween the baffle 360 and the door 310 effectively reduces or otherwiseeliminates the high field failure rates currently being experienced inthe marketplace with respect to the prior art baffle 116 that isthreadably affixed to the freezer door 110.

While the subject disclosure has been shown and described with referenceto preferred embodiments, those skilled in the art ,will readilyappreciate that changes and/or modifications may be made thereto withoutdeparting from the scope of the subject disclosure.
